PROBLEM TO BE SOLVED: To suppress the wear of each spring by providing a metal plate-made spring for pressing each roller in the same direction with respect to the circumferential direction, and making a part of each spring, which makes contact with the rolling surface of each roller, into a non-sharp end. SOLUTION: Both ends of a spring 4a formed by bending an elastic metal plate are bent laterally outward (mutually reverse directions) to form a lateral pair of pressing parts 14, 14. In the state where such a spring 4a is integrated into a roller clutch, each pressing part 14, 14 is inclined in the direction leaving the rolling surface of the roller 3 toward the tip. Accordingly, the protruding surface of each pressing part 14, 14 makes contact with the rolling surface of the roller 3 with a relatively wide area. Therefore, the surface pressure of the contact part of the pressing parts 14, 14 provided in one pair each for every spring 4a with the rolling surface of the roller 3 is reduced, and the wear condition of the spring 4a can be thus improved to suppress the wear of the spring 4a.
